What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study aims to understand the role of cirrhosis in promoting hepatocellular carcinoma (HCC) progression by analyzing the differential expression of long noncoding RNAs (lncRNAs) between cirrhotic hepatocellular carcinoma (CHCC) and noncirrhotic hepatocellular carcinoma (NCHCC).
methodsA transcriptional profile array was used to identify differentially expressed lncRNAs. Subsequently, a specific lncRNA was selected to evaluate the clinical significance, potential functions, regulatory targets, and pathways through both
resultsThe study identified a lncRNA, which we termed DERCNC, an acronym for Differentially Expressed RNA between Cirrhotic and Non-Cirrhotic HCC. DERCNC was significantly more highly expressed in CHCC than in NCHCC. Clinically, elevated levels of DERCNC expression were positively correlated with both the cirrhotic state and tumor stage and inversely correlated with tumor differentiation. Furthermore, high expression of DERCNC was associated with a poor prognosis for patients. Conditioned medium from the hepatic stellate cell (LX2) was found to enhance DERCNC expression, SOX9 expression, and tumor proliferation. Overexpression of DERCNC similarly promoted tumor proliferation and increased SOX9 levels. Conversely, DERCNC silencing resulted in the opposite effects. Moreover, the pro-proliferative function of DERCNC was reversible through the modulation of SOX9 expression. Further mechanistic studies revealed that DERCNC upregulated SOX9 by increasing the enrichment of H3K27ac modifications near the SOX9 promoter.
conclusionIn conclusion, DERCNC expression in CHCC has significant clinical implications and can aggravate tumor proliferation by targeting SOX9. This represents a novel mechanism by which cirrhosis promotes tumor progression.
